_InsertString inserts an empty string in this case, but I don't find
any tests for this. Could you add one?
There are also many over places (e.g. the 2nd half of _PaintItem) that
could use this helper. The goal is to have all reads of ->str go through
this helper, even in cases where the code is inside a HAS_STRINGS() block.
